Recent Advances in Spatially Coupled Codes: Overview and Outlook
Min Qiu, Xiaowei Wu, Peng Kang +2
The concept of spatial coupling is among the most significant breakthroughs in coding theory over the past decade. The excellent waterfall and error floor performance of spatially…
PAC Codes Meet CRC-Polar Codes
Xinyi Gu, Mohammad Rowshan, Jinhong Yuan
CRC-Polar codes under SC list decoding are well-regarded for their competitive error performance. This paper examines these codes by focusing on minimum weight codewords, breaking…
Reverse PAC Codes: Look-ahead List Decoding
Xinyi Gu, Mohammad Rowshan, Jinhong Yuan
Convolutional precoding in polarization-adjusted convolutional (PAC) codes is a recently introduced variant of polar codes. It has demonstrated an effective reduction in the number…
Weight Structure of Low/High-Rate Polar Codes and Its Applications
Mohammad Rowshan, Vlad-Florin Drăgoi, Jinhong Yuan
The structure of a linear block code is pivotal in defining fundamental properties, particularly weight distribution, and code design. In this study, we characterize the Type II st…
QoS Aware Transmit Beamforming for Secure Backscattering in Symbiotic Radio Systems
Mingcheng Nie, Deepak Mishra, Azzam Al-nahari +2
This paper focuses on secure backscatter transmission in the presence of a passive multi-antenna eavesdropper through a symbiotic radio (SR) network. Specifically, a single-antenna…
Segmented GRAND: Complexity Reduction through Sub-Pattern Combination
Mohammad Rowshan, Jinhong Yuan
The ordered-reliability bits (ORB) variant of guessing random additive noise decoding (GRAND), known as ORBGRAND, achieves remarkably low time complexity at high code rates compare…
